Why E-Commerce is different

Due to the exaggerated quality and handiness of web access several ancient tiny business square measure considering eCommerce as a sound and profitable sales channel. However, eCommerce and ancient commerce square measure terribly totally different, and it is vital to weight rigorously the variations between eCommerce and ancient commerce so as to choose if it might be a decent fit  your business or simply a pricey mistake.

Direct Interaction

Traditional commerce is commonly primarily based around face to face interaction. The client contains a likelihood to raise queries and therefore the staff will work with them to confirm a satisfactory group action. typically this offers staff a chance for upselling, or encourage the consumer to shop for a costlier item or connected things, increasing the look profits.

The client are going to be ready to bit and check the things, to form certain they're appropriate, and even attempt them on, that reduces the quantity of came things or complaints thanks to AN item not being as publicised on a list. or promotional leaflet. Expect a considerably higher rate of returns if you begin mercantilism on-line, as several can simply order and check out the things reception, and will not hesitate to come them as they'll roll in the hay by post while not having to speak with anybody personally.

Credit Card Fraud

The remote nature of ECommerce makes rather more tough to sight fraud, which implies stores will lose cash thanks to fraud. whereas ancient commerce isn't wholly secure, it's easier for a sales attendant to verify that the person shopping for one thing is truly the owner of the mastercard, by requesting photographic ID.

DIFFERENCE BETWEEN DSS, EIS AND MIS

With the exposure to all or any the on top of data systems, allow us to decide the variations between DSS and MIS. Table-1 enlists some basic variations between call network,Management systems and govt data System. because the name implies, the later 2 area unit the systems that offer data which will or might not be used for creating a call whereas the support data provided for selecting the policy, designing or implementation is that the basic element of DSS.
Let us decide the characteristics of the 3 systems :
DSS:
– DSS typically offer support for unstructured, or semi-structured choices (decisions that can't be delineated  in detail).
– DSS issues area unit usually characterised by incomplete or unsure information, or the utilization of qualitative knowledge.
– DSS can usually embrace modelling tools in them, wherever numerous various eventualities are often sculpturesque and compared.
– Investment choices area unit associate samples of people who can be supported by DSS
MIS:
 MIS is mostly additional subtle coverage systems engineered on existing dealing process systems
 Often wont to support structured higher cognitive process (decisions that may be delineated  thoroughly before the choice is made)
 Typically also will support military science level management, however generally area unit used at alternative levels
 Examples of structured choices supported by MIS may embrace selecting stock levels or the evaluation of product
